The present invention relates to a method for producing an alumite building material, which has excellent aesthetics such as design and is particularly suitable as an exterior material.

Description of the Related Art Conventionally, for anodized building materials excellent in corrosion resistance and aesthetics of this kind, a method of polishing anodized film (alumite) by buffing, a method of polishing by clear coating or electrodeposition coating. A method of buffing, chemically polishing or electrolytically polishing an aluminum base metal and then forming an anodized film to impart gloss is known.
【０００３】しかるに、上記の方法においては、陽極
酸化皮膜を高速回転のバフ研磨した場合、バフ目が粗い
ために陽極酸化皮膜の脱落が大きく、折角封孔処理した
部分をも削り取ってしまう結果となり、耐食性を著しく
低下させるという問題がある。また、バフ目が粗いた
め、研磨跡が残り美観においても自ら限界がある。However, in the above method, when the anodic oxide coating is buffed at high speed, the anodic oxide coating is largely dropped due to the rough buffing, and the portion subjected to the angle-sealing treatment is also scraped off. However, there is a problem that the corrosion resistance is significantly reduced. In addition, since the buffing is coarse, polishing marks remain and there is a limit in terms of aesthetics.
【０００４】次に、の方法においては、耐久性が不充
分で、従って、美観を保つには頻繁に塗装をし直す必要
があり、メンテナンスが厄介であるという問題がある。In the next method, there is a problem that the durability is insufficient and therefore it is necessary to repaint frequently to maintain the aesthetic appearance, and maintenance is troublesome.
【０００５】更にの方法は、陽極酸化皮膜自体は半透
明であるため、該皮膜により折角研磨した地金の光沢が
減じられ、そして耐久性を上げるために該皮膜を厚くす
ればする程、光沢が減失するという問題を孕んでいる。In a further method, since the anodized film itself is semitransparent, the film reduces the luster of the bare metal ground by polishing, and the thicker the film in order to improve durability, the more glossy it is. Has the problem of being lost.

い憾みがある。On the other hand, lacquer has a deep artistry that cannot be obtained by coating films of other paints, but it is expensive, has a high level of skill in coating technology, and its supply amount is decreasing year by year. However, there is a problem that it is difficult to use in the construction material field, which consumes a large amount.

法を、それぞれ内容とするものである。That is, the first aspect of the present invention is to:
Forming an anodic oxide coating on aluminum or an aluminum alloy and performing a sealing treatment, and then polishing the anodic oxide coating and the sealing treatment layer without substantially dropping or damaging the corrosion resistance and The second aspect of the present invention is a method for producing an anodized building material having excellent cosmetic properties. The second step is to form an anodized film on aluminum or an aluminum alloy and subject it to a sealing treatment. Then, the anodized coating and the sealing treatment layer are substantially formed. A method for producing an alumite building material excellent in corrosion resistance and cosmetics, characterized by performing a chromate treatment after polishing without causing the material to fall off or damage.

Black, wine red, primary electrolytic method and secondary electrolytic method,
It also includes gold, bronze, stainless steel color, etc. on which a colored anodic oxide film is formed. The sealing treatment method in the present invention is not particularly limited, and a conventional method of forming aluminum hydroxide by treatment with boiling water or heated steam is used, for example.

以上であることが好ましい。The polishing method in the present invention is not particularly limited as long as the anodized film and the sealing treatment layer are not substantially dropped or damaged. For example, buffing can be used if it takes sufficient time and is carefully polished, but it is unavoidable that the buffs have streaks. Therefore, lapping polishing is particularly suitable for obtaining a perfect mirror-like gloss without such a line. For example, a water break polishing method in which a mixed liquid of water and a polishing material such as ferrite or alumina is applied to and impregnated in a fibrous material such as felt, and planar lapping is performed is preferable. Abrasive grains having a grain size of 2 μm or less are preferable, and those having no corners are preferable. In addition, it is preferable that 250 to 300 g of the abrasive is mixed with 10 liters of water. The degree of polishing is preferably about 3 μm or less, and usually about 1 μm. The wrapping finish of the anodized film is 15 ~ for interior materials.
20 μm is preferable, and 20 μm for exterior materials
The above is preferable.

In order to close the above-mentioned pinhole or the pinhole caused by excessive polishing, it is desirable to further subject the above alumite building material to chromate treatment to form a chemical conversion film. An example of the composition of the chromate treatment bath and the treatment conditions is shown below. Chromate treatment bath composition: Potassium dichromate 15 g / l Phosphoric acid 0.15 g / l (PH: Neutralize with caustic soda to about 6.8) Chromate treatment condition: Bath temperature approx. 40 ° C Dipping (non-electrolytic) approx. 1 min The chromate-treated alumite building material obtained as described above has a further improved corrosion resistance and can retain its cosmetic properties for a longer period of time, so wind, rain, dust, exhaust gas,
It is particularly suitable as an exterior material placed in a harsh environment such as acid rain.

その有用性は極めて大である。As described above, the anodized building material obtained according to the present invention is excellent in corrosion resistance and light resistance because (1) there is substantially no loss of the anodic oxide film, not to mention the sealing treatment part. (2) In the case of polishing by lapping polishing, polishing marks are not left and the surface is mirror-like and the gloss and gloss are much better.
Further, the surface is like a glaze of pottery, is in a state of being positively ceramicized, and is extremely robust. (3) Since the anodized film itself is polished, even if the film itself is translucent,
(4) When forming a colored anodic oxide film that can produce gloss only with the surface layer, the colored layer rises up through the transparent polishing layer and becomes a so-called "color fading", which is a lacquer-like depth. You can get deep and interesting color effects. That is, it is possible to provide a stable and large quantity of lacquer, which is a color tone peculiar to an organic substance, with an inorganic substance such as aluminum (or an alloy thereof), and without requiring high technical skill like lacquer. (5) Since only the surface layer of the anodic oxide film needs to be polished, it can be easily re-polished at the construction site, and thereby a semi-permanently beautiful appearance can be reproduced and maintained. Therefore, the maintenance is very easy. (6) By closing the pinhole of the aluminum ingot, the pinhole of the anodized film, or the pinhole by polishing with the chromate treatment, the corrosion resistance is further improved,
It has many advantages such as being particularly suitable as an exterior material,
Its usefulness is extremely large.
